Iron rich chlorite
WebGangue minerals associated with sulfide-rich tailings include various aluminosilicate minerals such as chlorite, smectite, biotite, muscovite, plagioclase, amphibole, and pyroxene. Their contribution to acid-neutralization reactions has been examined in a number of field studies and through controlled laboratory experiments.
